CLAMP FOR SECURING TURN-TABLES FOR STRAW-STACKERS. I

SPECIFICATION forming part of Letters Patent No. 290,049, dated December 11, 18 83,

Application filed August 23, 1883. (No model.)

To all whom it may concern:

Be it known that I, LnwIs W. HASSELMAN, a resident of Indianapolis, Indiana, have made certain new and useful Improvements in Clamps for Securing Turn-Tables for Straw- Stackers, a description of which is set forth in the following specification, reference being made ,to the accompanying drawing.

My invention relates to devices designed to secure or clamp the turning tables of machines such as straw-stackers and the like, which are likely to be affected and turned by the force of the wind, and will be understood from the following explanation.

In the drawing I show it as attached to the frames of a straw-stacker, and refer to the machine shown in Letters Patent No. 10,347, reissued to me on the 3d of July, 1883. In all machines for stacking straw wherein a carrier is mounted on a frame so as to revolve in any direction, the machine,when at work in the field, is much affected by the wind, and the carrier is blown away from the place where it is desired to deposit the straw. Again, in other machines it is necessary that the machinery should be set up level, or the turntable will settle to the lowest point, while by using my device it may readily be clamped and secured in any position, whether it is set exactly level or not.

In the drawing, which presents a front view of my device,'F represents the lower sill of the revolving carrier-frame, to which the upper half of the turn-table I) is firmly bolted. H is the upper sill of the main frame; sha

sleeve connected with the upper half of the -my Letters Patent before cited, all this ma- To the sill F is chinery will be fully seen. bolted my clamping device, which comprises the angled arm ca, which has a short vertical arm, ca, at the bottom of which is a shorter horizontal lug or arm, cc the upper surface of which is-fitted to hug closely the under surface of the plate b. Through the arm ca a clamp-screw, 08, works againsta metal cap,

k, which holds an elastic gasket or rubber, or, closely and firmly against the upper face of the plate I).

When it is desired to clamp the machinery, the screw as is tightened with a wrench, and this brings the lug 0a up closely against the under side of the plate b, producing friction enough to hold it wherever it might be placed, so that no action of the wind or want of lev- 6o eling would cause the carrier to turn.

The screw as might be used without any elastic gasket, if the castings were turned smooth; but as the castings used in this class of machine are generally somewhat rough it is better to use some substance between the screw and plate which is elastic and will allow some play, and thus ease up the clamp in passing over inequalities of surface.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is the following:

1. In a straw-stacker, the combination,with the sills F H and the upper and lower sections of a turn-table, of the clamp formed with arms ca cc and lug 00R, and the clampscrew cs, bearing upon the upper section of the turn-table, substantially as described.

2. The combination of sill F, the clamparms ca ca, having lug 0a,, the upper and lower sections of the turn-table, the clamp-screw es,

the elastic gasket or, the sill H, shaft sh, and

sleeve 31, substantially as described. 3. The clamp herein described, in combination with the two halves of a turn-table, I

and means for securing and operating the same, so as to produce friction between the halves of the turn-table, substantially as described.

In witness whereof I have hereto set my hand this 20th day of August, 1883.

LEWIS \VM. HASSELMAN.
